These maps summarize the latest available COVID-19 outbreak data from Johns Hopkins University’s COVID-19 project, the City of St. Louis, and St. Louis County.
Unlike other interactive maps being used to track the outbreak, the initial three maps include the counties in Illinois and Kansas that are part of the St. Louis and Kansas City metropolitan areas. Kansas City is displayed here as if it were its own county. This is necessary because their public health department is reporting data for the city separate from the four counties that include parts of Kansas City.
The final map is also unique - it includes both the City of St. Louis and St. Louis County on one map and with a shared set of legend values, making direct comparisons possible. It shows Zip Code Tabulation Areas (ZCTAs), which are generalized areas that are roughly equivalent to USPS zip-codes. They are not 100% the same, however, and some homes with a given zip code may fall outside of ZCTA boundaries.
These maps are fully interactive. Clicking on a county will reveal some details about that place. You can navigate around them just as you would with Google Maps. You can zoom with your mouse or the plus and minus buttons in the upper-left corner of each map. You may also move the maps around by clicking with your mouse and dragging.
Due to lags in reporting, both at the public health department level and at Johns Hopkins itself, these numbers may lag behind other figures reported in the media. Data are based on confirmed tests and deaths, which are in turn biased by the lack of testing. The extent to which we are increasing testing may also make it seem like there are increases in cases, something known as “surveillance bias.” While we are almost certainly seeing spreading infection in Missouri communities, it is important to understand that increased testing is driving some of the observed increases in confirmed cases.
In addition to the interactive maps below, I regularly update a range of static maps and plots that capture the progression of the COVID-19 outbreak in Missouri, several metro areas, and at the ZCTA (zip code) level in St. Louis City and County. The most recent versions of each plot can be viewed by clicking on the links within the tabs below.

This first map uses data from the Kaiser Health Network to identify counties (in gray) without any hospitals as well as the number of ICU beds per 1,000 residents in counties that do have hospitals. Keep in mind that some hospitals may have expanded ICU bed capacity in anticipation of increased need.
For Kansas City, all hospital and ICU bed data have been allocated to Jackson, Clay, Cass, and Platte Counties. If you have a sense of number of beds in Kansas City, MO itself as opposed to the surrounding counties, please feel free to drop me an email.
This map shows confirmed infections as a rate per 1,000 residents. It is important not to map the raw counts themselves, but if you want to see those data, click on a county. You can also view the hospital infrastructure details from the first map for each county by clicking on them.
